What is the chance of pregnancy with an IUD?

We all know that the IUD is a method of contraception, but it is not a 100% contraceptive measure. Many women who have inserted the IUD also show signs of pregnancy. So, what are the chances of getting pregnant with an IUD? What should you do if you get pregnant with an IUD? Can you still keep the baby you got while using an IUD? Let me tell you about it below.

What is the chance of pregnancy with an IUD?

The IUD (also known as the contraceptive ring) mainly achieves the contraceptive effect by changing the geographical environment of the uterine cavity, affecting the development of sperm and egg combination and embryo implantation. It is widely accepted by women because of its safety, effectiveness, simplicity, economy and reversibility. At present, the key contraceptive ring used in clinical medicine is the copper-containing one (such as TCu200, TCu220C, etc.).

In recent years, some new types of slow-setting contraceptive rings have appeared, which can release small doses of therapeutic drugs locally in the uterine cavity. In addition to contraceptive measures, they also have the effect of treating some gynecological diseases. Although the IUD is a simple and safe contraceptive measure, it also has some side effects and complications. If the IUD is not properly placed, or does not match the size and shape of the uterine cavity, it may fall off or sink. The sinking of the IUD will affect the actual effectiveness of the contraceptive measure and cause pregnancy with the IUD.

Each IUD has a certain rate of falling off and pregnancy with the device. According to surveys, the one-year falling off rate of TCu200 is 5.61%, and the one-year pregnancy rate with the device is 1.51%. The morbidity of the new IUD is significantly reduced, and the 5-year cumulative drop rate and pregnancy rate with the IUD are both less than 1%. This shows that it is still possible for women of childbearing age to become pregnant after having an IUD inserted. If the pregnancy is confirmed, and the impact of the IUD on the test tube embryo is fully considered, it is not suitable for another pregnancy, and the IUD is contraindicated for medical abortion. An artificial abortion should be performed as soon as possible to terminate the pregnancy.

What are the possible reasons for pregnancy after IUD insertion?

1. If you have diabetes, your blood sugar is too high, the blood acid level increases, and the metal ring is corroded, affecting contraceptive measures.

2. The location of the ring is not right. If the contraceptive ring is not placed in the bottom of the uterus, it will not be effective as a contraceptive measure.

3. After the IUD is inserted, you engage in strenuous activities such as squatting, or sometimes during sexual intercourse, which causes the IUD to shift and fall off, leading to accidental pregnancy.

4. If the ring is not replaced in time for a long time, the ring will fall off or sink due to the monthly exfoliation of the uterine wall and menstrual stimulation.
